I’m not really following here how Cardinal Cupich’s reasoning applies to Pachamama.
I understand good inculturation. Many cultures had customs, architecture, vestments, and objects associated with the sacred and holy that were deeply ingrained in the consciousness of the culture–when these these things were present, the people immediately recognized sacredness.
To help such cultures recognize sacredness in Christianity, the Church often adapted such architecture, vestements, and other things that said to the culture loud and clear “this is sacred” (as far as was possible without falling into superstition or syncretism). They were used to show the sacredness of God, Christ, and Christian worship, not to reinforce the sacredness of pagan gods.
For example, a candle might indicate a prayer is being offered, or a chausable that a sacrifice is being offered–but these prayers and sacrifices were no longer offered to the pagan gods, but to the one true God.
Could you explain specifically how offering sacrifices of grains and other foods to Pachamama is inculturation?
My understanding is that this desire to offer sacrifice in thanksgiving for the fruits of the earth is a good thing, and it should be “Christianized” by explaining how such sacrifice of thanksgiving should be only offered to God, in particular in the Mass where the true Bread of Life is offered. Inculturation is not including the adoration of Pachamama or “mother earth” or any part of creation alongside the adoration of God. That is syncretism.
